Engadget was lucky enough to get its hands on a prototype of Sony's much-anticipated PlayStation Phone (believed to launch as the Xperia Play), and while not everything on the unit they got was finalized (Wi-Fi was completely broken), it does give us a pretty good idea of what to expect when the phone officially launches.

That single-core processor might seem disappointing with all the excitement surrounding Tegra 2 phones, but the Xperia Play still manages to get high marks in a number of benchmark tests (including a Quadrant score of 1,689).

Unfortunately, games made specifically for the "PlayStation Phone" couldn't be tested because they simply aren't available yet. Emulators had to fill that gap - psx4droid and GameBoid, specifically. As you can see in the video below, the games ran fairly well and were able to take control of the buttons on the gamepad (not the touchpads, however). Hopefully we can expect better performance out of games developed specifically for the system - perhaps some software tweaks might help.

It's important to stress that this is still a prototype, and there could be major changes before the phone is officially released. Still, it's hard to not be a little disappointed by the lack of a more powerful processor. Perhaps the Xperia Play was never going to be the gaming powerhouse many envisioned it as.
